Ministry of Education, Culture, Sports, Science and Technology: Grants-in-Aid for Scientific Research(基盤研究(A))
Project Year: 2005 - 2007    Investigator(s): Hiroshi NISHIHARA
The purpose of this study is to create intelligent molecular systems where the chemical and physical structures and the optical, magnetic and electronic properties are changed reversibly and then to produce "molecular functional devices" by combin...
Ministry of Education, Culture, Sports, Science and Technology: Grants-in-Aid for Scientific Research(特定領域研究)
Project Year: 2004 - 2007    Investigator(s): Hiroshi NISHIHARA
In this project, we aim at the construction of electro-functional interfacial space by assembling pi-conjugated and/or redox active metal complex molecular chains in one, two, or three dimensions. Bottom-up approach using successive coordination b...

Project Year: 2002 - 2006    Investigator(s): Kunihito KOUMOTO
Single crystals of homologous phase in the ZnO-In_2O_3 with layer structures were successfully grown by a flux method, and it was confirmed that the in-plane electrical conductivity is two orders of magnitude larger than cross-plane conductivity. ...
Ministry of Education, Culture, Sports, Science and Technology: Grants-in-Aid for Scientific Research(基盤研究(A))
Project Year: 2002 - 2004    Investigator(s): Hiroshi NISHIHARA
This project aims at the creation of new photochromic metal complexes, the investigation of their unique multiple functionalities, and the fabrication of novel types of molecular switches and memories by organizing them at the electrode surfaces. ...
